In order to develop Cambridge Crossing, DivcoWest was required to make improvements to Monsignor O’Brien Highway from Third Street to Museum Way. These improvements have included subsurface and surface infrastructure upgrades. This section of Monsignor O’Brien Highway is being transformed from a highway into a tree lined boulevard with bicycle lanes/cycle tracks, new sidewalks and significantly improved pedestrian crossings. Due to the construction associated with the MBTA’s Green Line Extension (GLX) Project, these improvements have been phased over several years.

Cambridge adopted the Specialized Stretch Energy Code in January 2023, which requires builders, for both new construction and major renovations, to meet high performance standards, prepare buildings for all-electric heating and hot water systems, and make parking facilities ready for electric vehicle charging equipment.

This certification recognizes how far the city has come in setting and meeting rigorous requirements to become carbon neutral by 2050.

Paint green bike lanes through the intersections on Massachusetts Avenue in Central Square and Hampshire Street in Inman Square to improve safety for drivers, bikers, and pedestrians.

To lead by example, the City of Cambridge is engaged in many initiatives aimed at improving the sustainability of municipal operations.

In 2009, the City set a goal to reduce residential trash disposal by 30% by 2020, and by 80% by 2050. With that goal in mind, the City expanded curbside food waste pickup to all buildings with 1 to 12 units. 25,000 households (8,100 buildings) are now eligible to participate.
